S355J2+N Steel Plate is a high-strength, low-alloy structural steel with specific mechanical and chemical properties. Here are some of the key properties of S355J2+N steel:

Yield Strength: The minimum yield strength of S355J2+N steel is 355 megapascals (MPa), hence the “355” in its name. This means the steel can withstand a certain amount of stress without undergoing permanent deformation.

Tensile Strength: The tensile strength of S355J2+N steel typically ranges from 450 to 680 MPa. It represents the maximum amount of stress the material can endure before breaking.

Elongation: S355J2+N steel usually has a high elongation percentage, which means it can stretch or deform significantly before failure. The specific elongation value can vary based on the thickness and product form.

Impact Resistance: S355J2+N steel is known for its good impact resistance. It has a minimum impact energy requirement of 27 Joules at -20°C (denoted as “J2” in the name), indicating its ability to absorb energy under impact conditions.

Normalized Condition: The “+N” designation signifies that the steel is supplied in a normalized condition, which means it has undergone controlled heat treatment to improve its mechanical properties, particularly toughness.

It’s important to note that the mechanical and chemical properties of S355J2+N steel can vary based on factors such as the plate thickness, heat treatment, and the manufacturer’s specifications. Therefore, it’s essential to consult the manufacturer’s data sheets and relevant standards (e.g., EN 10025-2) to ensure that the specific material used in your project meets your requirements.
